It's the day Connor has been waiting for his whole life. The day he is supposed to begin training as a knight.

Then why is everything going so wrong?

Connor and his friend Simon, a boy with a talent for magic, soon find themselves caught between goblins and skeletons in an ancient castle buried deep underground. When they stumble upon a talking skull locked in a birdcage, it could cost them their lives.

David Anthony, along with co-author Charles David Clasman, has written over 20 books for kids in three series, including Mystery Underground, Heroes A2Z, and Knightscares.

David Anthony received his first typewriter in the eighth grade and has been banging on keyboards ever since. As a child, some of David's best friends were books. He always loved to read. A friend first inspired him to write, and the steady encouragement of his parents and teachers kept him at it. Today he writes with the passion of his youth. No story can ever be too fantastic, too impossible, too spooky, or too silly.

David currently lives in West Bloomfield, Michigan with a patient wife, a semi-patient son, and a demanding dog. At least two of them usually need a haircut. When not writing or reading, David plays tabletop games with his son, engages in social media, and roots for the Detroit Red Wings.
